The roll has 12.5 square feet of material.
Multiply the two dimensions to get the area. The calculation will give you 720 square inches.
24 inches*50yards = 24 inches * 50*3*12 inches = 24 inches * 1800 inches = 43 200 square inches.
270 square feet.
A roll 2 foot by 30 foot contains 60 square feet. There are 144 square inches in a square foot. So the roll contains 8630 square inches = and you get all of these for 30 units of currency. I will assume that the unit of currency contains 100 smaller units. so the price is 3000 small units. This means that the cost per sq inch = 3000/8630 = 0.347 small units = just slightly more than one-third of the small unit.

300 square feet.
120 x 13.3 1596 inches
37.5 square feet.

There are 180 square inches in a roll of 1 inch x 10 yards. This is because 1 yard is equal to 36 inches, so 10 yards is 360 inches. Given that the width is 1 inch, the total area would be 1 inch x 360 inches = 360 square inches in the roll.
24 inches*50yards = 24 inches * 50*3*12 inches = 24 inches * 1800 inches = 43 200 square inches.
270 square feet.
12 yards x 360 yards = 4,320 square yards. 4320 sq yd = 4,320 x 36 x 36 square inches = 5,598,720 square inches

No. 12 inches by 12 inches = 144 square inches. To get 150 square inches from a roll 12 inches wide, you would need to buy 12.5 inches. That would measure exactly 150 square inches.
Easy way to figure it: If the roll is 3 feet by 100 feet, it would cover 300 square feet. But you have to overlap it about 6 inches at top and bottom, so once you subtract that, it would cover about 200 square feet., When figuring a job, add some for overlap at valleys, chimneys, etc. . . Hope this helps. A standard roll of 30# felt covers 216 square feet; one-half the area of a roll of 15# felt, which covers 432 square feet. Rows are overlapped 2 inches, not 6 inches.
